Our GY6 wheels fit a Honda Ruckus with a GY6 or any scooter with a GY6 engine. These wheels come in a 4/110 bolt pattern and come standard with a M10 bolt hole. If your hub has M12 bolt holes then just email and let me know and I will cut the bolt on the CNC when the design is cut. This is ideal but if you forget to email then you can easily open the bolt holes yourself by drilling with a half inch drill bit.
